To all whom it may. concern";

Be it known that L FRA N Envo, "J12, citizen of the United States,residing-at Geyserville, in the county of-Sonoma and State ofCalifornia, have'invented new and useful Improvements in-Engine-Primers, of

which the followingis aspecification...

This invention relates to internal combus tion engines, particularly topriming devices therefor, and has for its object the PI'OVlSlOIl ofmeans'whereby a'charge of-gasolene may be allowed toflow into alltheeylindersfst' multaneously'without the operators leaving the drivingseat, whereby to-facilitate starting the, engine .in. cold weather.; -s7 I An important object is the provision of a device of this characterincluding very simply and easily operated means {whereby all theprimingqcups associated. with the cylinders may be, simultaneouslyopened and separately controlled means. whereby. a

variable quantity of gasolene or other fuel may be admitted to'thecylinders. I

A further, ob'ect is the provision of a device of this characterwh-ichis provided with stop means whereby the operator may ascertain, withoutlooking, whether ;or notthe ple and inexpensive in priming cups areintheir open or closed po- SltlOIlS. Ji' I Anadditionalobject'isEtheprovision of a device of this character which will 'besimmanufacture, highly efficientin service, durable in use, easilyinstalled and a general improvement of the With the above andotherobjects and advantages in view ,'the inventionconsistszin thedetails of construction to be hereinafter... more fully described andclaimed, and illustrated in the accompanying drawings in which V IFigure 1 is a side elevation of an internal combustion engine showing mydevice applied thereto.

Fig. 3 is a front elevation of the priming tank.

Fig. 4 is a detail elevation of one of the primln cups showing the stopmember as sociate therewith and Fig. 5 is a detail view of the primingcup ing the letter A designates the front portion of an automobile and Bdesignates a n @siiefi ii eue re Patented Mar. 18,1919. Applicationfiled A gustes, 1 18., Serial No. 251,177.

broadly-by the letter D communicating with the cylinders of the engine.Each of these primingicups D comprises a valve body 10 provided at itslower end with a nipple 11 threadedinto the cylinder head of the engineand having a valve stem 12 upon the end of which is mounted a sprocketwheel 13; .A chain 14 is trained about all ofthe sprocket wheels 13 andextends through suitable openingsin the dash E of the automobile and istrained about a sprocket 15 mounted upon a bracket 16, secured upon the.front of the dash. The sprocket 15 is secured upon a shaft 17 .to whichis secured a treadle 18 de;

pressionof which will cause partial rotation ofthe shaft 17 and thesprocket 15. The shaft 17 further carries a shoe 19 which is engaged bya leaf spring 20 secured upon the dash for returning the shaft toitsoriginal position, after depression. From the above, it, will be seenthatdepression of the pedal ortreadle-18by the operator will result inmovement of the chain 14 which will turn all of the sprockets l3 andconsequently open the valves in the priming cups D.

I In order to provide means whereby the valves in the priming cups willbe opened to the proper extent, I provide upon one of the sprockets 13anarm 21- which will engageagainst opposite sides of an upstanding nipple22 formed on the priming cu body .110. -Engagement of the arm 21 withthis ',;nipple will prevent further movement of the sprocket 13.

Each of the priming cups 10 is provided with the nipple 22 to which isconnected by a suitable union 23 a pipe 24. All the pipes 24 extend inparallel relation to each other and extend through a suitable opening inthe dash E and communicate with the bottom of a priming tank 25 suitablymounted adjacent the dash E. At the points where the pipes 24 enter thebottom of the tank 25, are formed valve seats 26 normally closed byvalves 27 secured upon the lower ends of vertically extending rods 28WlllOh'GXtBIlCl upwardly and terminate albOVe the top of the tank 25.The tank 25 is of course provided with a suitable filling opening closedby any ordinary form of cap and is adapted to contain the gasolene orother fuel with which the engine is to be primed. A coil spring 29 isdisposed about each of the rods 28 and normally holdsthe valve 27 in aposition to close the opening. At each end, the tank has secured thereonan upstanding bracket or yoke 30 which is bifurcated as shown'and whichis provided'at one side with a plurality of teeth 31 meshing withpinions 3" secured upon the ends of a shaft 38 which extends -througheyes '34: formed on'the upper ends of the rods 28. Gneend of the shaft33 is provided With-a crank 3et bymeans of which the shaft may berotated.

In the operation of the device, after the opera-tor *has pressed atponthe treadle 18 to open the primin 'cups, :the crank 8% is grasped andturned, whereupon engagement of tl16plIllOl1S 32 with the teeth '31 on:the brackets will causethe shaft 33 tomove upwardly, pulling the rods28 upwardly and lifting the valves 27 from the seats 26 against theresilience of the springs '29. The gasolene or other fuel stored 'Withinthe tank 25 'Will then pass "through the tubesQd: and be discharged111t9'tl1BipIlH1l11g cups 'D from which it will pass into the cylindersof the engine. iVhen the engine has been primed, release of the crankhandle 3d "will permit the springs to return Ethe valves 27 to theiroriginal positions closing the openings to the pipes 24.

From the foregoing description and :a study of the drawings it will beapparent that I have thus providedn very sim'pledevice by means of whichthe cylinders of an internal combustion engine 1118;) be very quicklyand QilSllY primed to facilitate starting in eold weather o'r foranyother desired purpose.
